Application March 19, 1940, Serial No. 324,801

3 Claims. (Cl. 66-190) It is a further object of my invention to provide a fabric of the aforementioned character with elastic strands incorporated into the fabric in such manner as to prevent a slipping thereof,-

, thereby obviating an uneven bunching up of the fabric at scattered portions thereof.

Another object of this invention is to providev reinforcement for the elastic elements in a fabric `oi. the above-described character.

Still a further object is to minimize the forma- 20 ,tion of extensive-runs caused by dropped stitches.

' And it is within the contemplation of my invention to present a fabric of the above-mentioned characteristics that can be readily fabricated on conventional knitting machines,

Other objects, features and advantages will appear from the drawing and the descriptionhereinafter given.

Referring to the drawing, Figure l is a representation of a shirred fabil ric embodying one form of my invention.

Figure 2 is a somewhat enlarged diagrammatic representation of a form of fabric of my invention, showing the relationship of the elastic yarn, the tuck and the jersey stitch yarn, and Figure 3 is an enlarged diagrammatic representation of the fabric substantially like that of Figures 1 and 2, showing the relative positioning of the various stitches employed, when the elastic yarn is in its fully elongated condition. In the drawing, the' fabric of the particular form of my invention illustrated comprises the basic mit portions il), and the reinforced elastic portions li including the regions substantially within the limits of the; brackets in Figures 2 and -3. Each basic knit portion I0 is formed of the body yarn I2 and consists, in the fabric illustrated, of the jersey stitches i3, although itis understood that 'other forms and designs of stitches may be employed in said basic knit portion within the scope and intent of this invention. Each of said portions II contains the tuck stitch courses I4 and I5, respectively, both adjacent thev elastic yarn I6 incorporated with the fabric in a manner to be hereinafter set forth,

' 55 said two tuck stitch courses being in anking relation to said yarn I6. In the preferred arrangement, the tuck stiches in courses I4 and I5 are formed in alternatev wales, those in course I4 being in the odd numbered wales, such as the Wales identied by the reference numerals I1 and I9,- 5 and those in course I5 beingin the even numbered wales, such as the wales identified by reference numerals I8 and 20. In this manner,

' any. dropped stitches in the wales below elastic yarn I6 will be kept from running above said l0 yarn I6, as will become evident from the further description hereinafter given.

Embodied in the fabric in said portion II is the double yarn 2lv which is formed with undulating stitches alternately disposed Ain front of l5 and behind said elastic yarn IB. Although a double yarn is illustrated, it is also Within the contemplation of my invention to employ any other type of reinforcing yarn means of increased proportions or strength. It will be observed that 20 the free portions 22 of the tuck stitches are not knitted into the fabric, thereby enabling the formation of the relatively long loops 23 and 24, the excess yarn in such loops being taken from the said tuck stitches. 25

'I'he elastic yarn is incorporated into the fabric while in its elongated condition, and extends 'in a straight line alternately behind loops 26 of the double yarn 2l in one wale, and between the single and double yarn loops 24 and 23, respective- 30 ly, inthe next Wale.

It is important to'note that the regions 25 of the elastic yarn I6 are firmly tied in between the long loops 2t and 24, thereby preventing slippage between the elastic-and .the interlock- 35 ing yarns. The use of the relatively heavy double yarn 2| enhances this tying-in effect, inasmuch as that portion of loop' 23 behind region 25 is sufficiently bulky to force elastic yarn I6 against loop 2t; and in this manner said loops 23 and 40 24 cooperate to frictionally hold the elastic yarn against slippage. Furthermore, the double yarn.

'2i or the equivalent thereof serves the additending folds 21, substantially as indicated in Figure l.

The material not only has the presentable apl pearance of a uniformly shirred effect, but also yit has the utilitarian advantages of form-fitting elasticity, rendering it adaptable for a variety of uses. With strands it of very considerable elasticity, a very decided puckering can be effected.

According to the preferred form `of this invention, the tuck stitch courses it'. and l5 are at the region of the elastic strand iii, so as to remove these necessarily coarse and unsightly stitches from the body or basic knit portions l@ of the fabric. Being adjacent the various elastic strands I6, they do not adversely aect the appearance of the fabric, andk yet are permitted to serve their utilitarian functions. Furthermore, by keeping the tucking courses at the upper and lower edges of the regions i0, there is no interruption to the vertical continuity of the puckering folds except Vat the lines of the elastic strands i6. Y

The Ybody yarn i2 can be of any desired properties, but it is essential that the elastic yarn l be of considerably greater elasticity and capable of being elongated to a considerably greater extent. The spacing between the elastic yarns it can be varied according to requirements.

It is of course understood that the above description is merely illustrative of the fabric of my invention, and that other forms and modifications thereof may be made Within the scope oi. the appended claims. Y

What I claim is:

1. A. puckered fabric comprising a basic knit portion with spaced verticalvv folds and an elastic portion incorporated in said basic portion, the

tending straight across and being tied in between forwardly and rearwardly disposed knit loops in predetermined wales so that upon a. stretching of the elastic strand the knit loops will be correspondingly moved with it, certain of said knit loops tying in the elastic strand constituting a course of yarn structurally stronger than the yarn in the basic knit portion.

2. A puckered fabric comprising a basic knit portion with spaced vertical folds and an elastic portion incorporated in said basic portion, the elastic portion containing an elastic strand disposed along a course extending transversely with respect tothe Wales of the fabric, said strand extending straight across and being tied in between forwardly and rearwardly disposed knit loops in predetermined wales so that upon a stretching of the elastic strand the knit loops will be correspondingly moved with it, certain of said knit loops tying' in the elastic strand constituting a course of yarn of greater crosssectional area than that of the yarn in the basic knit portion.

3. A puckered fabric comprising a basic knit portion with spaced vertical folds and an elastic portion incorporated in said basic portion, the elastic portion containing an elastic strand disposed along a course extending transversely with respect to the wales of the fabric, a reinforcing course of knit loops in saidl elastic portion formed of a double thread of yarn, said elastic strand extending straight across and being tied in between certain knit loops of said reinforcing course and interlocking knit loops of the next adjacent course in predetermined wales.
